It's our nature as creatures.I am with you. I have no idea why people are so dumb with all the well educated people are here. I think there is a systematic state of denial which is cultural and discounts academic information. I see that in my profession and neighboring professions as well. Some of my my peers with better education from Eastern or MidWest School, in comparison to the locals; have been similarly critical of the local cultural discount on evidence based studies or quality of the regional eduction.
It's called fear. And we are all susceptible to it.
It's how we deal with it that matters.
Or, as a childhood mentor would say, "Knowing is half the battle!"
